How can I check PCI slots remotely?

How can I check how many PCI slots are used/free on a remote server to which I have no physical access?

Maby you mean

Code:

lspci

But how do I interpret the Total/Free/Used PCI slots from lspci's output?

Code:

I don't know that one but maby the man for lspci would give you a hint? If not, try to google for it or something. google.com/linux is great if you google for Linux-related stuff.

win32sux · 02-22-2005, 10:19 AM

okay... i'll read the manual for lspci to see what i find...

as for googling, i always make sure i google (and search LQ) before opening a new thread...

win32sux · 02-23-2005, 03:39 PM

well, i went through the lspci manual and didn't have any luck (maybe i'm just retarded)...

i still haven't figured-out how to see the Total/Free/Used PCI slots remotely...

here's the verbose output on the machine which's PCI slots i'm trying to analyze:

does anyone know how to determine the Total/Free/Used PCI slots from this output??

or perhaps i can determine this info with some other command(s)??

you know... there are *subtle* ways to bump a thread.. detailing what you've foind since your last post etc...

there's never goign to be a direct reliable way to relate the internal layout of pci busses compared to the physical layout, and per system it will change again in different ways.

Code:

ok, so.... 01:00 is the agp slot, as it's on it's own bus (and contains a video card... always a giveaway!)
i would then assume that your pci slots are 00:09 and 00:0b, so at least all values inclusive will also be slots. and the rest is onboard stuff, with the integrated peripherals on bus 00, slot 01.

you're right... i should really know better by now... sorry about that, acid_kewpie... =(

thanks for the info... i really appreciate it... =)

win32sux · 03-05-2005, 07:24 AM

okay, so i now know that there are exactly TWO pci slots being used (each one with a realtek network card)...

given this, i could determine the amount of free pci slots by subtracting two from the total amount of slots...

i can determine the total amount of slots by looking at the board's specs on a website...

so i can solve my problem if i can find a way to (remotely) determine the motherboard brand and/or model number...

does anyone know how to (remotely) determine a motherboard's brand and/or model number??

i'm gonna google about this, but any input you could share with me would be greatly appreciated...

win32sux · 03-05-2005, 07:53 AM

okay, i've found this:

http://ezix.sourceforge.net/software/lshw.html

looks like it might be what i need... i'm gonna try it tonight... i haven't read the documentation yet, but the output examples look really cool...

=)

lshw doesn't tell us free/open expansion slots unfortunately. I've got an Intel DG43NB board in my server. It has 3xPCI, 2xPCI-e 1x, 1xPCI-e 16x, 1xPCI-e 1x. The 3xPCI are currently occupied, but none of the PCI-e expansion slots are occupied.

Code:

In answer to your question of how to acquire the Motherboard version model number, check this:

Code:

fermulator@fermmy-server:~$ sudo dmidecode -t baseboard
# dmidecode 2.9
SMBIOS 2.4 present.

Handle 0x0002, DMI type 2, 15 bytes
Base Board Information
	Manufacturer: Intel Corporation
	Product Name: DG43NB
	Version: AAE34877-402
	Serial Number: U********** (starred out)
	Asset Tag: To be filled by O.E.M.
	Features:
		Board is a hosting board
		Board is replaceable
	Location In Chassis: To be filled by O.E.M.
	Chassis Handle: 0x0003
	Type: Motherboard
	Contained Object Handles: 0

I am also interested to know how one can determine if there are open expansion slots remotely.
